True of False:

Vitamins and minerals are very important to health, they are absorbed without any change during digestion. (     )

The human body needs fatty acids, and it can make all but two of them—linoleic acid (the 18-carbon omega-8 fatty acid) and linolenic acid (the 18-carbon omega-3 fatty acid). (     )

Sometimes a nonessential amino acid might become essential under special circumstances. (    )

the cells of the pancreas do not make the protein hemoglobin, which is needed only by the red blood cells.                                      (     )

When nutrients enter the body from the digestive tract, the stomach receives them first; then it metabolizes, packages, stores, or ships them out for use by other tissues. ( )

Acetyl CoA can readily make fat. And glucose.                   (     )

Choose the best answer to the following questions:

Which of the following sugar is NOT a monosaccharide:          (     )    

1. Glucose (B) Fructose (C) Galactose (D)Maltose

Which of the following statement about fatty acid is WRONG:     (      )

(A) All of the energy-yielding nutrients—protein, carbohydrates, and fat—can be broken down to acetyl CoA.

(B) Acetyl CoA can enter the TCA cycle or it can make fat.

(C) In the end of Energy Metabolism, oxygen is consumed, water and carbon dioxide are produced, and energy is captured in ATP

(D) Fatty acids can be used to make glucose.

In estimating energy requirements, the DRI Committee developed equations based on research measuring total daily energy expenditure. These equations consider how the following factors influence BMR and consequently energy expenditure, which of the following is not included:                         (      )

(A)Gender. (B) Race (C)Age. (D) Physical activity.

For building fitness and minimizing the risk of overuse injuries, which of the following tip should be considered:

1. Be active all week, exceptt on the weekends.

(B) Use proper equipment and wear proper attire while doing dangerous exercises.

(C) Perform exercises using proper form.

(D) Include warm-up and cool-down activities in the beginning and at the end of exercise.

1. The higher the blood pressure is above normal, the greater the risk. Low blood pressure is generally a sign of long life expectancy and low heart disease risk.. What is your recommendation on “how to implement a Heart-Healthy Diet”.

2. What is the harmful effects of excessive fiber intake?

3 To be more healthy, what would you Plan a Healthy Diet with a daily variety of foods .

4 Some fats in the diet are essential for good health, but others can be harmful. For this reason, recommendations focus both on the quantity and the quality of the fat in the diet. Both the amounts and types of fat in the diet influence the risk for disease. Please give 3 or more examples to illustrate the point.

• How have you seen this at work in your own community?

Multiple Choice

(1) When energy derived from ATP hydrolysis is coupled to an endergonic enzymatic reaction, which of the following is the most likely mechanistic description of this coupling?

a. ATP binds at a regulatory site and puts the enzyme in a more active conformation.

b. ATP binds at one active site of the enzyme and the substrate(s) bind at another.

c. Hydrolysis of ATP provides the energy for the endergonic reaction at the active site where the substrate(s) are bound.

d. ATP and substrate compete for binding to the same active site.

(2) End product feedback inhibition of multistep pathways is a major mechanism for cellular regulation. In this proccess, the

a. product of the last enzyme inhibits the substrate of the last enzyme.

b. product of an early metabolically irreversible enzyme inhibits the last enzyme in the pathway.

c. An early regulatory enzyme in the pathway is inhibited when ATP concentrations are depleted.

d. product of one of the last enzymes inhibits an early regulatory enzyme in he pathway

(3) The conversion of glucose to pyruvate is a multistep process requiring ten enzymes. If a mutation occurrs resulting in a lack of activity for one of these enzymes, which of the following happens?

a. the concentration of the metabolic intermediate which is the substrate of the missing enzyme is likely to increase and accumulate.

b. the cell will produce more of the other nine enzymes to maintain steady state.

c. the concentration of the metabolic intermediate which is the product of the missing enzyme will increase

d. pyruvate production will increase, leading to feedback regulation of the pathway

Jo Question: Dealing with credit transactions

On Monday, Jo goes out and buys 20 trees for $120 each from Georgie the tree seller and pays $1200 with a debit card, and the seller agrees that Jo can pay another $1200 later on. Jo also thinks that trees are getting expensive and looks around for another seller. The sales are not very good and Jo only sells 2 trees for $250 each, so he decides to start selling trees on the Internet on Q-bay. By the end of the week Jo has sold 2 trees to Da for $250 each and 3 to Fa for $300 each, Da and Fa both promise to pay by Waypal. Jo has also had to buy packaging for $300 and has opened up an account with Pack and Go who say they will send a bill for the goods. In the shop Jo has sold 10 more trees for a total of $3000. Jo pays $2000 into the bank and sends Georgie an electronic transfer for $1000.The following week Jo finds a new supplier of trees called Dando and buys another 25 trees for $2500, which he pays with a debit card. Jo receives a waypal payment for $500 from Da, but nothing from Fa. Jo sells 5 trees on Q-bay for $1200 to Jay, who promises to pay by waypal.

What is the closing Trial Balance for Jo ?

Which of the following statements about enzyme substrate complexes is TRUE?

B. The enzyme concentration is higher than the substrate concentration under physiological conditions.

C. Alteration in the conformation of the enzyme may occur when substrate binds.

D. Increase in enzyme concentration does not affect the rate of the reaction.

Materials costs of $969000 and conversion costs of $1372500 were charged to a processing department in the month of September. Materials are added at the beginning of the process, while conversion costs are incurred uniformly throughout the process. There were no units in beginning work in process, 190000 units were started into production in September, and there were 10000 units in ending work in process that were 30% complete at the end of September. What was the total amount of manufacturing costs assigned to the 10000 units in the ending work in process?
